Egor Baranov updated IGNITE-28747:
----------------------------------
Ignite Flags: (was: Docs Required,Release Notes Required)
> GridToStringBuilder#handleRecursion may cause NPE
> -------------------------------------------------
>
> Key: IGNITE-28747
> URL: https://issues.apache.org/jira/browse/IGNITE-28747
> Project: Ignite
> Issue Type: Bug
> Reporter: Egor Baranov
> Assignee: Egor Baranov
> Priority: Major
>
> When recursion occurs on the end of string builder it may cause NPE.
> Possible solution: override #i in class SBLimitedLength to execute the same
> logic as in methods #a
> Here is exception stack trace:
> {code:java}
> [2026-06-03T11:53:10,217][ERROR][test-runner-#181143%internal.IgniteDiscoveryMassiveNodeFailTest%][IgniteDiscoveryMassiveNodeFailTest0]
> Got exception while starting (will rollback startup routine).
